The compounds of formula (I) may contain in their structure a tautomeric system and consequently these compounds may be present in each of their tautomeric forms.

Preferred compounds within the invention are those wherein Y is a radical of formula (a) or (b), wherein X, Z, A and B are as described hereinabove, provided that A and B, taken together, do not form a radical of formula (f) or (g) when Y is a radical of formula (b).

The most preferred compounds within the invention are:

cis-1-butyl-3-[4-[4-[4-[[2-(2,4-dichlorophenyl)-2-(1H-1,2,4-triazol-1-ylmethyl)-1,3-dioxolan-4-yl]methoxy]phenyl]-1-piperazinyl]phenyl]-2,4-imidazolidinedione;

cis-1-[4-[4-[4-[[2-(2,4-dichlorophenyl)-2-(1H-1,2,4-triazol-1-ylmethyl)-1,3-dioxolan-4-yl]methoxy]phenyl]-1-piperazinyl]phenyl]-3-propyl-2-imidazolidinone;

the pharmaceutically acceptable acid addition salts and the stereochemically isomeric forms thereof.

In order to simplify the structural representations of the compounds (I) and of certain starting materials and intermediates used in the preparation thereof, the 2-Ar-2-(1H-imidazol-1-ylmethyl or 1H-1,2,4-triazol-1-ylmethyl)-1,3-dioxolan-4-yl group, wherein Ar is as previously defined, will hereafter be represented by the symbol D: ##STR5##

The compounds of formula (I) can generally be prepared by O-alkylating an appropriately substituted phenol of formula (III) with a reactive ester of formula (II). ##STR6##

In formula (II), W has the meaning of a reactive ester residue such as, for example, halo, preferably chloro, bromo or iodo, or a sulfonyloxy group such as, for example, methylsulfonyloxy or 4-methylphenylsulfonyloxy and the like.

The said O-alkylation reaction is conveniently conducted in a suitable reaction-inert solvent or a mixture of such solvents. Suitable reaction-inert solvents are an oromatic hydrocarbon, e.g., benzene, methylbenzene, dimethylbenzene, and the like; a lower alkanol, e.g., methanol, ethanol, 1-butanol and the like; a ketone, e.g., 2-propanone, 4-methyl-2-pentanone and the like; an ether, e.g., 1,4-dioxane; 1,1'-oxybisethane, tetrahydrofuran and the like; N,N-dimethylformamide (DMF); N,N-dimethylacetamide (DMA); hexamethylphosphoric triamide (HMPT); dimethyl sulfoxide (DMSO); nitrobenzene; 1-methyl-2-pyrrolidinone; and the like. The addition of an appropriate base such as, for example, an alkali metal carbonate or hydrogen carbonate, sodium hydride or an organic base such as, for example, N,N-diethylethanamine or N-(1-methylethyl)-2-propanamine may be utilized to pick up the acid which is liberated during the course of the reaction. It may be advantageous previously to convert the substituted phenol (III) into a metal salt thereof, preferably the sodium salt, in the usual manner, e.g., by the reaction of (III) with metal bases such as sodium hydride, sodium hydroxide and the like, and to use thereafter said metal salt in the reaction with (II). Somewhat elevated temperatures are appropriate to enhance the reaction rate and most preferably the reaction is carried out at from about 80° C. to about 130° C.

Additionally, the compounds of formula (I) may also generally be prepared by cyclizing an intermediate of formula (IV) with an amine of formula (V) or by cyclizing an amine of formula (VI) with an intermediate of formula (VII). ##STR7##

The reaction is carried out by stirring the reactants together in the presence of an appropriate polar solvent, e.g., water, in admixture with an appropriate water-miscible organic solvent such as, for example, 2-propanol, 2-propanone and the like, preferably at an elevated temperature, in order to enhance the rate of the reaction, and, most preferably, in the presence of an appropriate alkali- or earth alkali metal iodide such as, for example, potassium iodide.

The compounds of formula (I) can also be prepared by N-alkylating a piperazine of formula (VIII) with an appropriately substituted benzene of formula (IX) or by N-alkylating a piperazine of formula (XI) with a benzene of formula (X). ##STR8##

Said N-alkylation reaction may be carried out in the usual manner, e.g., by stirring the reactants together, preferably at somewhat elevated temperatures in an appropriate organic solvent such as, for example, dimethylsulfoxide, N,N-dimethylformamide and the like, in the presence of an appropriate base such as, for example, an alkali metal hydride or carbonate.

The compounds of formula (I) may also be derived from a compound of formula ##STR9## wherein R⁵ is hydrogen and R⁶ is an appropriate leaving group or R⁵ and R⁶, when taken together, represent a direct bond, by cyclizing a said compound of formula (XII) with a derivative of formula

    H--Z--A--B--L                                              (XIII),

wherein L is an appropriate leaving group.

The said cyclization-reaction can generally be conducted in a suitable reaction-inert solvent such as, for example, an alcohol, e.g., butanol and the like, an ether, e.g., tetrahydrofuran, 1,4-dioxane and the like. Although the cyclization reaction may be conducted at room temperature, somewhat elevated temperatures are appropriate to enhance the rate of the reaction. Preferably the reaction is conducted at the reflux temperature of the reaction mixture. Suitable catalysts, e.g., N,N-dimethyl-4-pyridinamine, may also enhance the rate of the reaction.

In some cases it may be advantageous to conduct the herein above-described cyclization reaction with a derivative of formula

    H--Z--A--B--L'                                             (XIV),

wherein L' is a precursor of a leaving group, e.g. an alcohol function, to isolate the thus formed intermediate of formula ##STR10## to convert the L'-group into a suitable leaving group L, e.g. by converting an alcohol into a chloride function, and, finally, to cyclize the thus obtained intermediate of formula ##STR11##

The compounds of formula (I) wherein Y is a radical of formula (a) wherein Z is NR¹, said compounds being represented by the formula (I-a), can also be prepared by cyclizing an intermediate of formula (XVII) with an appropriate reagent of formula (XVIII). ##STR12## The said cyclization reaction is generally conducted following the same procedures as previously described herein for the preparation of (I) starting from (XII) and (XIII).

The compounds of formula (I), wherein Y is a radical of formula (b) wherein X is NR² and Z is NR¹, said compounds being represented by the formula (I-b) may be prepared by a cyclodesulfurization reaction of an intermediate of formula (XIX). ##STR13##

Said cyclodesulfurization reaction may be carried out by the reaction of (XIX) with an appropriate alkyl halide, preferably iodomethane in an appropriate reaction-inert organic solvent, e.g., a lower alkanol such as methanol, ethanol, 2-propanol and the like. Otherwise, the cyclodesulfurization reaction may be carried out by the reaction of (XIX) with an appropriate metal oxide or salt in an appropriate solvent according to art-known procedures. For example, the compounds of formula (I) can easily be prepared by the reaction of (XIX) with an appropriate Hg(II) or Pb(II) oxide or salt, such as, for example HgO, HgCl₂, Hg(OAc)₂, PbO or Pb(OAc)₂. In certain instances it may be appropriate to supplement the reaction mixture with a small amount of sulfur. Even so methanediimines, especially N,N'-methanetetraylbis[cyclohexanamine] may be used as cyclodesulfurizing agents.

The compounds of formula (I) wherein Y is a radical of formula (b), wherein --AB-- is a bivalent radical of formula (g), said compounds being represented by the formula (I-c), can be prepared by reacting an intermediate of formula (XX) in an acidic aqueous solution, e.g. an aqueous hydrochloric, hydrobromic, sulfuric and the like acidic solution with a carbonyl-generating agent, e.g., formic acid and the like. ##STR14##

The compounds of formula (I) wherein Z is NH, said compounds being represented by the formulae (I-d-1) respectively (I-d-2) can be converted into a compound of formula (I) wherein R¹ is other than hydrogen, said R¹ being represented by the formula R^(1-a) and said compounds by the formulae (I-e-1) respectively (I-e-2), by reacting the former with a reagent of formula (XXI), wherein W represents a reactive leaving group, following art-known N-alkylation reactions. ##STR15## said N-alkylation reaction may be carried out in the usual manner, e.g., by stirring the reactants together, preferably at somewhat elevated temperatures in an appropriate organic solvent such as, for example, dimethyl sulfoxide, N,N-dimethylformamide and the like, in the presence of an appropriate base such as, for example, an alkali metal hydride or carbonate.

The 1H-imidazole- and 1H-1,2,4-triazole-derivatives of formula (I), obtained in base form in the foregoing preparations, may be converted to their therapeutically active non-toxic acid addition salt forms by treatment with appropriate acids, such as, for example, inorganic acids, such as hydrohalic acid, e.g. hydrochloric, hydrobromic and the like, and sulfuric acid, nitric acid, phosphoric acid and the like; or organic acids, such as, for example, acetic, propanoic, hydroxyacetic, 2-hydroxypropanoic, 2-oxopropanoic, ethanedioic, propanedioic, butanedioic, (Z)-2-butenedioic, (E)-2-butenedioic, 2-hydroxybutanedioic, 2,3-dihydroxybutanedioic, 2-hydroxy-1,2,3-propanetricarboxylic, methanesulfonic, ethanesulfonic, benzenesulfonic, 4-methylbenzenesulfonic, cyclohexanesulfamic, 2-hydroxybenzoic, 4-amino-2-hydroxybenzoic and the like acids. The salts are in turn converted to the corresponding free bases in the usual manner, e.g., by reaction with alkali such as sodium or potassium hydroxide.

From formula (I) it is evident that the compounds of this invention have at least two asymmetric carbon atoms in their structures, namely those located in the 2- and 4-position of the dioxolane nucleus, and consequently they can exist under different stereochemically isomeric forms. The stereochemically isomeric forms of (I) and the pharmaceutically acceptable acid addition salts thereof are intended to be embraced within the scope of this invention.

The diastereomeric racemates of (I), denoted as cis and trans forms respectively, according to the rules described in J. Org. Chem. 35 (9), 2849-2867 (1970), may be obtained separately by conventional methods. Appropriate methods which may advantageously be employed therefore include, for example, selective crystallization and chromatography separation, e.g., column-chromatography.

Since the stereochemical configuration is already fixed in a number of intermediate compounds, e.g., in intermediates of the formulas (II), (IV), (VI), (VIII), (X), (XII), (XV), (XVI), (XVII), (XIX) and (XX), it is also possible to separate cis and trans forms at this or even an earlier stage, whereupon the corresponding forms of (I) may be derived therefrom in the previously indicated manner. The separation of cis and trans forms of such intermediates may be performed by conventional methods as described hereabove for the separation of cis and trans forms of the compounds (I).

It is evident that the cis and trans diastereomeric racemates may be further resolved into their optical isomers, cis(+), cis(-), trans(+) and trans(-) by the application of methodologies known to those skilled in the art.

A number of the intermediates and starting materials used in the foregoing preparations are known compounds, others may be prepared according to art-known methodologies of preparing similar compounds and some of them are novel and consequently their preparation will be described hereafter.

The intermediates of formula (III) can generally be derived from an intermediate of formula (XXII), wherein P is an appropriate protective group, following art-known procedures. ##STR16##

The procedures for eliminating the protective group P depend upon the nature of P. For example, where P is a methyl group the reaction can be conducted in an acidic hydrolyzing medium, containing a strong non-oxidizing mineral acid, e.g., hydrobromic acid in glacial acetic acid.

The intermediates of formula (XXII) can be obtained by cyclizing an intermediate of formula (XXIII) with an amine of formula (XX) following the same procedure as described for the preparation of (I) starting from (IV) and (V). ##STR17##

The starting materials of formula (V), wherein Y is a radical of formula (a) or (b) wherein Z is NR¹, said Y being represented by Y' and said (V) by (V-a), may be prepared by cyclizing a reagent of formula (XXIV) with a reagent of formula (XXV) following the cyclization reaction which is previously described herein for the preparation of the compounds of formula (I) starting from (XII) and (XIII). ##STR18## In (XXIV) P' represents hydrogen or an appropriate protective group, in which case the said protective group shoud be eliminated after the cyclization reaction.

The starting materials of formula (V) may also be derived from the corresponding nitro-derivatives following art-known nitro-to-amine reducing procedures.

The intermediates of formula (XXII) may also be derived from an intermediate of formula ##STR19## by reacting the latter with a reagent of formula (XIII) following the previously described cyclization procedures for the preparation of compounds of formula (I) starting from (XII) and (XIII).

The intermediates of formula (XII) may be derived from an amine of formula (XXVII) by reacting the latter with a reagent of formula (XXVIII) or carbon disulfide thus yielding an intermediate of formula (XII-a), respectively an intermediate of formula (XII-b). ##STR20##

The intermediates of formula (XVII), (XIX) and (XX) can conveniently be prepared by reacting an intermediate of formula (XII) with an appropriate amine derivative.

The intermediates of formula (XII-a), wherein R⁶ is a radical of formula Z¹ -R⁷, said intermediates being represented by the formula ##STR21## wherein Z¹ is O or NR⁸, said R⁸ being hydrogen, Ar or lower alkyl optionally substituted by Ar, and

R⁷ is hydrogen, Ar, amino or lower alkyl optionally substituted by a member selected from the group consisting of hydroxy, Ar-amino, lower alkylamino or carboxy or substituted with up to tow lower alkyloxy radicals,

provided that:

Z¹ is other than O where R⁷ is hydrogen; and

where R⁷ is amino, Z¹ is other than NH or O;

said intermediates, the pharmaceutically acceptable acid addition salts and the stereochemically isomeric forms thereof display strong antimicrobial properties themselves and both as useful intermediates herein and as antimicrobial substances they constitute an additional feature of this invention.

It is evident from the structure of the intermediates of formula (XII-a-1) that the stereochemical isomery as described hereinabove for the compounds of formula (I) applies also for the said intermediates and acid addition salts thereof.

The compounds of formula (I), the intermediates of formula (XII-a-1), the pharmaceutically acceptable acid addition salts and stereochemically isomeric forms thereof are useful agents in combatting fungi and bacteria. For example, said compounds are found to be highly active against a wide variety of fungi such as, for example, Microsporum canis, Ctenomyces mentagrophytes, Trichophyton rubrum, Phialophora verrucosa, Cryptococcus neoformans, Candida tropicalis, Candida albicans, Mucor species, Aspergillus fumigatus, Sporotricum schenckii and Saprolegnia species, and against bacteria such as, for example, Erysipelotrix insidiosa, Staphylococci such as Staphylococcus hemolyticus and Streptococci such as Streptococcus pyogenes. In view of their potent, local as well as systemic, antimicrobial activity the compounds of this invention constitute useful tools for the destruction or prevention of the growth of fungi and bacteria and more particularly they can effectively be used in the treatment of subjects suffering from such microorganisms.

The strong antimicrobial activity of the compounds (I) and the intermediates (XII-a-1) is clearly evidenced by the data obtained in the following experiments, which data are only given to illustrate the useful antimicrobial properties of all the compounds (I) and the intermediates (XII-a-1) and not to limit the invention either with respect to the scope of susceptible microorganisms nor with respect to the scope of formula (I) or (XII-a-1).

Experiment A: Oral treatment of vaginal candidosis in rats.

Female Wistar rats of ±100 g body weight were used. They were ovariectomized and hysterectomized and after three weeks of recovery, 100 g of oestradiol undecylate in sesame oil was given subcutaneously once a week for 3 consecutive weeks. The thus induced psuedo-oestrus was controlled by microscopic examination of vaginal smears. Food and water were left available ad libitum. The rats were infected intravaginally with 8.10⁵ cells of Candida albicans, grown on Sabouraud broth for 48 hours at 37° C. and diluted with saline. The date of infection varies from day +25 to day +32 after surgical intervention, depending on the appearance of signs of induced pseudo-oestrus. The drugs under investigation were administered orally once a day for three days starting from the third day after infection. For each experiment there were placebo treated controls. The results were assessed by taking vaginal smears with sterile swabs on several days after the infection. The swabs were put into Sabouraud broth in petri-dishes and incubated for 48 hours at 37° C. If no growth of Candida albicans occurs, i.e., when the animals were negative at the end of the experiment, this was due to drug administration because it never happens in placebo-treated controls. The first column in the Tables I, II and III give the lowest oral dose in mg/kg of the drug under investigation which is found active at the 14th day after infection.

Experiment B: Topical treatment of vaginal candidosis in rats.

Female Wistar rats of ±100 g of body weight were used. They were ovariectomized and hysterectomized and after three weeks of recovery, 100 ug of oestradiol undecylate in sesame oil was given subcutaneously once a week for 3 consecutive weeks. The thus induced psuedo-oestrus was controlled by microscopic examination of vaginal smears. Food and water were left available ad libitum. The rats were infected intravaginally 8.10⁵ cells of Candida albicans, grown on Sabouraud broth for 48 hours at 37° C. and diluted with saline. The date of infection varies from day +25 to day +32 aftersurgical intervention, depending on the appearance of signs of inducing pseudo-oestrus. The drugs under investigation were administered topically twice a day for three consecutive days starting from the third day after infection. For each experiment there were placebo treated controls. The results were assessed by taking vaginal smears with sterile swabs on several days after the infection. The swabs were put into Sabouraud broth in petri-dishes and incubated for 48 hours at 37° C. If no growth of Candida albicans occurs, i.e., when the animals were negative at the end of the experiment, this was due to drug administration because it never happens in placebo-treated controls. The second column in the Tables I, II and III give the lowest concentration of the drug under investigation which is found active at the 7th day after the last topical administration of the drug.

Experiment C: Oral treatment of Microsporum canis infections in guinea pigs.

Adult Albino guinea pigs were prepared by clipping their backs and infected on the scarified skin by scratching five 3 cm long transverse cuts with Microsporum canis (strain RV 14314). The animals were housed individually in wire mesh cages and food and water were available ad libitum. The drugs under investigation were administered orally once a day for 14 consecutive days starting 24 hours before infection. For each experiment there were placebo treated controls.

The animals were evaluated 21 days after infection by microscopic examination of the skin and by cultures on Sabouraud agar comprising a suitable bacterial antibiotic and a suitable agent to eliminate contaminating fungi.

The third column in Tables I, II and III give the lowest oral dose in mg/kg of the drug under investigation at which no lesions were observed and at which there was no culture growth.

Experiment D: Topical treatment of Microsporum canis infections in guinea pigs.

Adult Albino guinea pigs were prepared by clipping their backs and infected on the scarified skin by scratching five 3 cm long transverse cuts with Microsporum canis (strain RV 14314). The animals were housed individually in wire mesh cages and food and water were available ad libitum. The drugs under investigation were administered topically once a day for 14 consecutive days starting the third day after infection. For each experiment there were placebo treated controls. The animals were evaluated 21 days after infection by microscopic examination of the skin and by cultures on Sabouraud agar comprising a suitable bacterial antibiotic and a suitable agent to eliminate contaminating fungi.

The fourth column in Tables I, II and III gives the lowest concentration of the drug under investigation at which no lesions were observed and at which there was no culture growth.

The compounds listed in Tables I, II and III are intended to illustrate and not to limit the scope of the present invention.

In view of their antifungal and antibacterial properties this invention provides valuable compositions comprising the compounds of formula (I), (XII-a-1), acid addition salts or stereochemically isomeric forms thereof, as the active ingredient in a solvent or a solid, semi-solid or liquid diluent or carrier, and, in addition, it provides an effective method of combatting fungal or bacterial growth by use of an effective antifungal or antibacterial amount of such compound (I), (XII-a-1) or salts thereof. Antifungal and antibacterial compositions comprising an effective amount of an active compound (I) or (XII-a-1), either alone or in combination with other active thereapeutic ingredients, in admixture with suitable carriers may be readily prepared according to conventional pharmaceutical techniques for the usual routes of administration. Preferred compositions are in dosage unit form, comprising per dosage unit an effective quantity of the active ingredient in admixture with suitable carriers. Although the amount of the active ingredient per unit dosage may vary within rather wide limits, dosage units comprising from about 1 to about 500 mg and more particularly from about 10 to about 250 mg of the active ingredient are preferred.

To prepare the pharmaceutical compositions of this invention an antimicrobially effective amount of the particular compound or compounds, in base or acid-addition salt form, as the active ingredients, is combined in intimate admixture with a pharmaceutically acceptable carrier, which carrier may take a wide variety of forms depending on the form of preparation desired for administration. These pharmaceutical compositions are desirable in unitary dosage form suitable, preferably, for administration orally, rectally or by parenteral injection. For example, in preparing the compositions in oral dosage form, any of the usual pharmaceutical media may be employed, such as, for example, water, glycols, oils, alcohols and the like in the case of oral liquid preparations such as suspensions, syrups, elixirs and solutions; or solid carriers such as starches, sugars, kaolin, lubricants, binders, disintegrating agents and the like in the case of powders, pills, capsules and tablets. Because of their ease in administration, tablets and capsules represent the most advantageous oral dosage unit form, in which case solid pharmaceutical carriers are obviously employed. For parenteral compositions, the carrier will usually comprise sterile water, at least in large part, though other ingredients, for example, may be prepared in which the carrier comprises saline solution, glucose solution or a mixture of saline and glucose solution. Injectable suspensions may also be prepared in which case appropriate liquid carriers, suspending agents and the like may be employed. Acid addition salts of (I), due to their increased water solubility over the corresponding base form, are obviously more suitable in the preparation of aqueous compositions.

It is especially advantageous to formulate the aforementioned pharmaceutical compositions in dosage unit form for ease of administration and uniformity of dosage. Dosage unit form as used in the specification and claims herein refers to physically discrete units suitable as unitary dosages, each unit containing a predetermined quantity of active ingredient calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. Examples of such dosage unit forms are tablets (including scored or coated tablets), capsules, pills, powder packets, wafers, injectable solutions or suspensions, teaspoonfuls, tablespoonfuls and the like, and segregated multiples thereof. The amount of active ingredient per dosage unit is from about 0.25 mg to about 100 mg and, preferably from about 0.5 to about 20 mg.

The following formulations exemplify compositions typical for the treatment of vaginal candidosis in dosage unit form suitable for systemic or topical administration to animal and human subjects in accordance with the instant invention.

EXAMPLE XLI

A mixture of 4.2 parts of 3-[4-[4-(4-hydroxyphenyl)-1-piperazinyl]phenyl]-1-(1-methylethyl)-2,4-imidazolidinedione, 4.3 parts of cis-2-(2,4-dichlorophenyl)-2-(1H-imidazol-1-ylmethyl)-1,3-dioxolane-4-methanol methanesulfonate (ester), 1.4 parts of potassium carbonate and 120 parts of 4-methyl-2-pentanone was stirred and refluxed for 72 hours. The reaction mixture was cooled and poured onto water. The product was extracted with dichloromethane. The extract was washed with water, dried, filtered and evaporated. The residue was purified by column chromatography over silica gel using a mixture of trichloromethane and methanol (99.5:0.5 by volume) as eluent. The pure fractions were collected and the eluent was evaporated. The residue was crystallized from 4-methyl-2-pentanone. The product was filtered off and dried at 120° C., yielding 1.9 parts (25%) of cis-3-[4-[4-[4-[[2-(2,4-dichlorophenyl)-2-(1H-imidazol-1-ylmethyl)-1,3-dioxolan-4-yl]methoxy]phenyl] -1-piperazinyl]phenyl]-1-(1-methylethyl)-2,4-imidazolidinedione; mp. 177.6° C.
